Dogs & Black Widow Spider Bites

Black widow spiders (Latrodectus mactans) are tiny insects only three to 10 millimeters long. Their colors range from dark gray to black, and the mature black widows have classic red hourglass shapes on their abdomens. Black widow spiders love warm climates and are typically found in the southern part of the United States. Bites can occur when dogs go for walks outside, or the spider becomes trapped or accidentally stepped on.

You must understand the symptoms of a black widow spider bite. Their venom contains a neurotoxin that can cause clinical signs related to the nervous system. Diarrhea and vomiting are among the most common symptoms of spider bites. Furthermore, it is common for pain and swelling to occur at the site of the bite.

Now, let’s get to the most important part of the article. What do you do if a black widow spider has bitten your dog? An antivenin is available to address black widow spider bites, but not all animal hospitals have access to it. Supportive care will be necessary. Fluids will be provided for support, and muscle relaxers can help the dog with tremors and twitching. Vets will often treat spider bites with the same therapies used for allergic reactions, and pain medication will be necessary if the bite site is swollen or causing your dog discomfort.

Black widow spider bites need to be taken seriously, especially for those who live in warmer climates. A black widow spider bite can cause gastrointestinal symptoms and severe neurological problems. Contact your veterinarian immediately if you suspect a black widow spider has bitten your dog.
